Flash: how to change text of button with ActionScript?

you give the new symbol and instance name in the properties panel, and then you reference it like this...

newNameOfInstance.mytext.text = "abc";


rp / ZA

that's what I tried but it doesn't work:

I createt a text-field (dynamic-text) and named the instance "mytext"
then I convert this to a symbol named "sym1"
now I make an instance of that symbol and name it "newNameOfInstance"
in the action-script I write the following code:

newNameOfInstance.mytext.text = "abcd";

and I get the error: ReferenceError: Error #1069: property mytext for flash.display.SimpleButton not found ...

are you sure you are giving the item an "Instance name" and not just naming the symbol? when you turn it into a symbol, you name it... then in the properties panel, you give it an instance name.
one other thing...  is your symbol a movieclip or a button?  you should never use buttons... they are not needed... you should be using movieclips

That's true. I use buttons and if I change it to a movieclip it works. But I want that when I move the cursor on the symbol that I get the "hand-cursor" and can catch "onclick-events" as with buttons. How I have to do this (I'm new in flash-programming)?

here is the standard for AS 3.0 button (movieclips)

btnName.addEventListener( MouseEvent.CLICK, on_Click);
btnName.addEventListener( MouseEvent.ROLL_OVER, on_RollOver);
btnName.addEventListener( MouseEvent.ROLL_OUT, on_RollOut);
btnName.buttonMode = true;

function on_Click( evt:Event ):void
{
   trace("you clicked --> " + evt.target.name);
}

function on_RollOver( evt:Event ):void
{
   trace("you rolled over --> " + evt.target.name);

}

function on_RollOut( evt:Event ):void
{
   trace("you rolled out of --> " + evt.target.name);

}


hope this helps...

nearly everything ok except the user can not see the "hand"-cursor and he doesn't know that this is a button. How to solve this?

buttonMode = true should make that work...

but you can also use...

btnName.useHandCursor = true;

the aim is not far: I have to set both, buttonMode and useHandCursor.  my last question: that works (I made a MovieClip with a rectangle and a text) in the part of the rectangle but not in the part of the text-field. Have aou a solution for that?

Great, you are a really an expert! Thanks a lot!!
